The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body.

No one nor anything can silence me.

There exists everywhere a medium in things, determined by equilibrium.

Elements which are similar as regards their chemical properties have atomic weights which are either of nearly the same value (eg. Pt, Ir, Os) or which increase regularly (eg. K, Ru, Cs).

Work, look for peace and calm in work: You will find it nowhere else. Pleasures flit by -- they are only for yourself; work leaves a mark of long-lasting joy, work is for others.
